MELTING-FURNACE.

SPECIFICATION forming part of Letters Patent No. 753,122, dated February23, 1904.

Application filed August 9, 1902.

To all whmn it may concern:

Be it known that I, HENRI J. J. CHARLIER, a citizen of France, residingin Philadelphia, Pennsylvania, have invented certain Improvements inMelting-Furnaces, of which the following is a specification.

My invention consists of certain improvements in the melting-furnace forwhich I obtained Letters Patent of the United States numbered 687,557,dated November 26, 1901, the objects of my present invention being to soconstruct the furnace as to more effectively utilize the heat and topermit the use of the same opening in the furnace casing or shell, bothas a charging-opening and as a pouringopening. These objects I attain inthe manner hereinafter set forth, reference being had to theaccompanying drawings, in which Figure 1 is a longitudinal section of myimproved melting-furnace. Fig. 2 is a transverse section of the same onthe line a a, Fig.

1; and Fig. 3 is a section on the same line, but showing the furnacedischarging its molten contents. i

In Fig. 1 of the drawings, 1 represents the cylindrical shell of thefurnace, and 2 and 3 the opposite heads of the same, the head 2 having aprojecting trunnion 4:, adapted to a bearing 5, and the head 3 having atubular trunnion 6, adapted to a bearing 7, the furnace-casing having arefractory lining 8, which is extended in the form of a contracted neck9 through the hollow trunnion 6. The valved oil-supply pipe isrepresented at 10, and the valved air-supply pipe is shown at 11, all ofthese parts of the furnace being substantially similar to those of thepatented furnace. I

The feed-hopper consists of a tapering casing 12 with refractory lining13, and said feed-hopper in the present instance instead of beinglocated at that end of the furnace remote from the neck 9 is locatedadjacent to said neck, whereby the products of combustion injected intothe furnace through the Y neck 9 are caused to traverse the entirelength of the furnace and after striking the far end of the same arecaused to return toward the neck before being permitted to escapethrough the feed-hopper, the reverberating effect thus Serial No.119,016. (No model.)

obtained materially increasing the heating effect of the flame andmaintaining an increased temperature in the receiving-chamber of thefurnace. In the present instance also the charging-hopper is detachablefrom the easing of the furnace, the lower portion of the hopper fittinginto the tapering opening 14, formed in the shell and lining of the bodyof the furnace, and said hopper having a projecting flange 15, whichbears upon the shell of the furnace and serves to steady the hopper inposition thereon without interfering with the ready withdrawal of thehopper when necessary. By this means the hopper-receiving opening 14 inthe main casing of the furnace can be utilized as a pouring-opening, asshown in Fig. 3, when the melting operation has been completed and thenecessity of forming a special pouring-opening in the furnace is therebyobviated.

My present invention can, as will be evident, be embodied in furnacesintended to use natural gas fully as well as in furnaces using oil fuel.

Having thus described my invention, I claim and desire to secure byLetters Patent 1. The combination of the body of the furnace having at.one end an opening for receiving the products of combustion, withacharging-hopper through which the products of combustion escape fromthe furnace, said charging hopper being located adjacent to that end ofthe furnace which receives the products of combustion,whereby areverberating effect of the latter within the body of the furnace isobtained, substantially as specified.

2. The combination of the body of the furnace pivotally mounted so as toturn about its longitudinal axis and having at one end an axial openingfor receiving gaseous products of combustion, with a combined feedingand pouring opening located in the peripheral portion of the body of thefurnace closer to that end of the same which receives the products ofcombustion than to the other end, substantially as specified.

3. The combination of the body of a furnace pivotally mounted so as toturn about its longitudinal axis and having at one end an axial openingfor receiving gaseous products of combustion, With a combined vent andto this specification in the presence of two sub-' pouringopeninglocated in the peripheral porscribing Witnesses.

tion of the body of the furnace closer to that end of the same Whichreceives the products HEN-RI CHARLIER' 5 of combustion than to the otherend, substan- Witnesses:

tially as specified. WILL A. BARR,
